Product details

Temperature grade and environment

Rated for -40°C to 85°C ambient, the MAX1523EUT+T suits industrial environments: outdoor telecom enclosures, factory-floor sensor supplies, and battery-powered instrumentation where the board sees seasonal temperature swings. The SOT-23-6 package keeps the footprint small, but thermal performance depends on the external MOSFET and diode — those components see the real dissipation.

Sourcing and lifecycle

Lifecycle status is Active per the manufacturer, with ROHS3 compliance. For volume commitments or BOM freeze planning, this is a stable line — no imminent obsolescence signal.

Frequently asked questions

What is the exact function of MAX1523EUT+T?

It is a current-mode PWM controller IC that drives an external transistor in boost, flyback, or SEPIC converters. It regulates the output by modulating the duty cycle of the external switch, with a maximum duty cycle of 85%.

Can MAX1523EUT+T be used in a SEPIC converter?

Yes, SEPIC is one of the supported topologies alongside boost and flyback. The controller operates as a transistor driver, so an external coupling capacitor and inductor are needed to implement the SEPIC stage.
